  3. Design a particular Steel or a Stainless Steel, describe how to heat-treat it, what kind of microstructure will develop and what will be its final mechanical properties.
  4. Explain the different Processing Methods of Advanced Ceramics (Powder metallurgy, milling, die-pressing, Sintering) and the different Classification of Polymers (Thermoplastic, Thermosetting, Elastomers) and their engineering applications.
  5. Describe the different types of Composite Materials (Particulate, Fiber and Laminar Composites), their processing and suggest different composites for different engineering applications.
  6. Explain the fundamentals of Corrosion (Chemical Corrosion, Electrochemical Corrosion, Oxidation) and use the existing methods to prevent it.
  7. Use non-destructive Testing Methods, identify proper instrumentation and apply them to different engineering materials.
  8. Use thermocouples to measure temperature profiles and optical microscopy to observe microstructures.
